Ecology
Yserthrax is one of the elder species, claiming a wide territory and shaping the ecology around it for centuries. It is most often found in planar regions. It is gargantuan-sized, which shapes how it hunts, hides, or fights. As a legendary creature, it is rare in the world and likely the only specimen of its kind in the local region.
Behaviour
Yserthrax is intelligent, vain, long-memoried; it remembers slights for centuries and rewards loyalty in kind. Its alignment varies by individual or is irrelevant — it acts on instinct, drive, or whoever commands it. It is intelligent enough to plan, scheme, or remember.
Origin
Yserthrax is introduced in MCDM's Flee, Mortals! (2023). Dragons in D&D canon trace to Bahamut and Tiamat, with each lineage having its own founding myth. Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
